[sdiy] LM3900 to CD40XX Connection?

[Fahl, Romeo]

I'm taking a shot at cloning the Random Voltage Source from the Buchla 208/Music Easel.  You can see the schematic for it at this URL:

In the original, one LM3900 stage is used for the clock input, which is then pumped into a CD4016 switch, which looks to me like it's being used as a buffer.  its output drives the clock input of the CD4015.  

I'm trying to avoid using a CD4016, since I have no need for any other CMOS switches in the circuit.  Could I simply use a transistor buffer (Emitter Follower)  instead?
